Mine was running perfectly for about 3 months, no issues then all of a sudden last week it stopped saving files (any files) in my Samsung Note 3…I’ve tried formatting in the phone, now with SanDisk Adapter on my PC…this ■■■■■! Luckily I was able to copy all my files over to my PC prior…so once (hopefully) I do get the SD fixed I can reload the files
I am also a victim… I never believed SanDisk can fail so when my first 64gb micro sd card failed on my galaxy note 2 last year I blamed it on samsung but a 2nd one just failed 2 days ago…
Apparently, when they fail u neither can copy to it or delete files already in it nor format it… I hv tried formatting it with all possible procedures n it cannot be formatted. …This is a huge let down on SanDisk. … I hv three 16gb SanDisk I bought like 3 to 4 years back n also a 32gb version n they have never failed me but in less than a year, two 64gb ultra SanDisk hv failed me…I am so much heartbroken and like u rightly said please no one should buy an ultra 64gb SanDisk cos it fails more when u get to the 40gb limit…I am presently using a third 64gb ultra SanDisk micro sd card on my galaxy note 10.1 n hv already accepted my faith that it may fail someday. … its time to move on to a new brand… am done with SanDisk for now…This is very very bad from u SanDisk. …
THE SANDISK MOBILE ULTRA 64GB MICRO SD CARD HAS FAILED ME TWICE & I CURRENTLY BLINDLY PURCHASED A THIRD ONE BEFORE THE SECOND ONE FAILED. … I ALREADY KNOW MY FAITH WITHOUT IT…PLEASE & PLEASE DONT BUY IT
I would like to add my voice to the list of defective Sandisk 64gb micro sdxc card. Hardly use it and now I can’t reformat or delete the contents. I have tried every tools and tricks on both Windows and Linux and Android OS. The card is defective and it is a worry!
Yes they can replace it… I just received shipment of two 64gb micro sd cards that also failed in same manner like yours… contact their support and if u still have your failed micro sd card. …u will be answered
I personally do not have a SanDisk Micro SD, but I do have a 4GB Sansa Clip+. I also have a 64GB Micro SDXC which I was able to reformat to FAT32 and use on my Clip+. I learned the hard way that Windows is unable to properly detect a 64GB SDXC card. I had to use an SDXC card reader for it to be read. Normally SD cards have an SD adaptor that you could use to insert on your laptop or any other card reader, trust me, I tried but only worked with an SDXC card reader I had to buy separately. I tried a lot of software to format the card to FAT32 but the only one that worked was RMPrepUSB. I do hope this helps a lot of you out there. Let me know how it goes.
thats fair enough. i am having the same problem as everyone.
however, what happenes to the personal date and photos store in the car that no longer allowes formatting?
are we to simply trust SanDisk with our private content? mu card is within warranty and i want a new one but do not wish to hand over my personal conten stored on the card.
so what is the way forward seeing that i can not remove such content and do not trust SanDisk ( i.e. see what happend to sony - same could happen to SanDisk)
That is really not helping - this is a forum, please post the answer here to the question so we can all see it rather than everyone pointlessly asking the same question to Sandisk support.
I also have a failed 128GB micro SDXC card (just suddenly stopped being able to write to it, has around 75GB on it right now and worked fine up to that point) which has personal data on it I want to wipe before returning it for a warranty replacement. My card seems to be stuck in the write protect mode described in this thread, is there an way to override it temporarily to wipe the card? I have the data I want from it so I don’t need the card to protect its data.
My own 64GB micro SDXC card has failed in exactly the same way as everyone elses.
As I am unable to wipe my personal data from the card due o this widespread fault I am also not prepared to send the card with the data intact to Sandisk for replacement.
I will be emailing/chatting to Sandisk about this later today and I will report what they say later. I will suggest that I would be prepared to return the card if I can cut it into two pieces to ensure the data is destroyed. I think this would be a sensible solution.
